Given numbers are 861, 231, 997, 694

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(861, 231) = 9471

GCD(861, 231) = ( 861 x 231 ) / 9471

= 861 / 231

= 861

Step2:

LCM(21, 997) = 20937

GCD(21, 997) = ( 21 x 997 ) / 20937

= 21 / 997

= 21

Step3:

LCM(1, 694) = 694

GCD(1, 694) = ( 1 x 694 ) / 694

= 1 / 694

= 1

So, Greatest Common Divisor of 861, 231, 997, 694 is 1
